To all whom it may concern;- I

Be it knownthat I, FRANK R. HAHN, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Building Units and Ties for Same, of which the fo lowing is a specification.

This, invention relates to improvements in building units and tying means for the same and the rincipal object is the provision of a cast building unit having a tying element cast therein which will serve as a means whereby the unit may be secured to studs or posts-of a building construction in a single wall construction or wherebythe opposed units of a double wall construction may be secured or tied together.

A further object of this invention is the provision of a building unit of plastic material havin a tying means cast therein and projecting rom the upper rear edge of the Th same, the tying means being strong and flexible to accommodate itself to various working conditions. 7

To the accomplishment of these and other objects which will be set forth hereafter, the invention consists in the construction, combination and arrangement of parts hereafter described and then defined 1n the claims, reference being bad to the afccompanaying drawings forming a part hereof and which show for the purpose of illustrative disclosure, preferred and other forms of my invention, it being expressly understood that changes ma be made in practice without digressing rom my inventive idea as defined in the claims.

In the drawings:

Fig. 1 represents a front view of a building unit constructed according to my in vention.

Fig. 2 represents a rear view thereof.

Fig. 3 represents a erspective view of a wall construction utilizing a building unit embodying my invention.

Fig. 4 re resents a perspective view of a unit of slightly difi'erent form.

Fig. 5 represents a view in end elevation of a double wall construction utilizing a building unit constructed according to my invention. 7

Fi 6 re resents a doub e wal units constructed according to my invention.

Referring now to the drawings, the nuperspective view of a construction utilizing building I mere] 1 designates one form of building unit. This is preferably composed of plastic material and is of slab shape, being of general rectangular form and having tongues 2 formed on certain edges and grooves 3 on other edges whereby adjacent units Wlll be interlocked when fitted together. It is to be noted that these tongues and grooves are preferably formed so as to leave the flat faces or shoulders 4 on each. side thereof, though of course this is not essential. It is also to be noted, as shown in Figure 2 of the drawing that these units may be formed preferably on their rear face with a plurality of panels 5 separated by the parts 6 of the normal thickness -of the units.

When these elements 7 are embedded therein. As shown these tying elements are preferably formed of a stri of sheet metal corrugated laterally of itsel so as to be flexible and strong. ey are preferably positioned at an angle and extend from near the front face of the unit through the top edge thereof leaving, the free end portion 8. extending upwardly at an angle therefrom. The free end 8 of the tying element 7 preferably emerges from the top edge of the unit near the rear edge thereof, and, of course, being flexible may be bent readily in an desired direction. By this arrangement the tying elements do not interfere with the roper fitting together of the units.

When the units 1 are formed with the panels 5, the tying elements are embedded in the thicker portions ditional securit It is to be noted that the tongue 2 may cut away-as at 9 for the purpose of exposing the tying element 7 and permittin access thereto by a hammer or other imp ement in installing. The thicker parts of the units might advantageously be placed in line with and against the studs or posts. j

In the single wall construction as shown in Figure 3, the free ends of the tying elements are secured by nails, screws or other suitable means to the osts or studs 10, and if any slack remains t erein, the weight of the unit above will take it up. The recesses left by the cutaway parts 9 of the tongue 2 may be filled with suitable plastic ma- ,terial.

In the form shown in Figure 4, the building unit 11 is cast in molds so as to imitate the appearance of wooden siding and the 6 for purposes of adunits 1 are formed, the tying erection.

, strips,

only in connection with a single wall con-' struction, but it is also applicable to and useful in a double wall construction, as

shown in Figures 5 and 6. The same ref-' erencecharacters are of course used in these figures. The tying elements 7 are of sufficient length to extend across the wall and to rest on the other part thereof being held in place by the uppgr units. The tongues 2 may or may not cut away to provide 0 enings 12 to receive the ends of the tying e ements whereby the are held in proper position while the we lis in the process of Of course the overlapping or rather extending the tying elements from both parts of the wall to the other results in great security andstability; 7

While I have described t e tying elements as bein formed of corrugate sheet metal it is to be understood that other material may be used and that these tying elements ma be secured and used in other ways from t o'se herein described.

What I claim is:

1. A building unit of lastic material having a tying element em dded therein and extending u wardly from the rear edge thereof, sai tying element ,being formed of a strip of corrugated metal.

2. A building unit of plastic material having a' tying element embedded therein and extending upwardly from the rear edge thereof, said tying element being formed of a strip of metal corrugated transversely thereof.

3. A building unit of general rectangular shape of plastic material and having a tongue formed on one edge and a; groove formed onthe other edge, to interfit with ad acent units, a tying element embedded therein and extendmg upwardly from the edge havingthe tongue, part of thetongue bemg cut awayto permit access 'to the tying element.

4. A building unit formed to provide a plurality of panels separated by parts of greater thickness, said building unit having a tongue formed on one edge and a groove formed on the other edge to interfit with t units, a plurality of tying elements corresponding groove on another e ge, flexible tying elements embedded in each unit and having free ends extending from the upper edge of each unit, said tying elements extendi from one part of the wall to the other, said tongues being cut away to provide open ngs'to receive the free ends of the tym elements, the tying elements being held in p ace by the unit next above.
